They are obtained by creating a combo weapon without a proper combo card. Although a scratch card will provide the proper combination for weapons, it does not have the full benefits as having the correct combo card. With a scratch card, you are unable to use a weapon's strong attack, and the PP gained from using that weapon will be halved.
- A proper combo card, when found, will replace a scratch card and give the player the ability to use a combo weapon's alternate attack, and restore the proper PP payout.
- It is impossible to get a Scratch Card for the Wingman, as well as the Zap N' Shine in Dead Rising 2: Off the Record. As soon as you make these combo weapons, it gives you a combo card for it.
